Application August 16, 1955, Serial No. 528,657 '3 claims. (c1. 12s-3) This invention relates to a machine for chipping one face of a brick `in order to produce what is known as a rockface or chipped brick.

An object of this invention is to provide an improved structure whereby the outer face of brick may be shaped by chipping in a continuous process.

Another object of this invention is to provide a brick chipping machine which is simple in construction and embodies a pair of rotatable chipping wheels with a conveying means for moving the brick past the chipping wheels.

A further object of this invention is to provide in a machine of this kind a yieldable holding means for holding the brick during the chipping operation so that the brick will not crack or break at any point which would render the brick useless.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Fig. 2 is a plan view of the machine.

Fig. 3 is an end elevation looking at the forward end of the machine.

Fig. 4 is a sectional view taken on line 4--4 of Fig. l.

Fig. 8 is a fragmentary sectional view taken on line 8-8 of Fig. l.

Referring to the drawings the numeral 10 designates generally a frame structure which includes outer upright legs 11 and 12 and inner upright legs 13 and 14. A longitudinal frame member 15 is connected to the outer and inner legs at one side of the machine and end frame bars 16 and 17 are connected to the upper ends of the end legs 11 and 12, respectively. A longitudinally extending guide 18 is carried by the frame 10 and as shown in Fig. 8, the guide 18 is formed of a pair of conventional L- shaped guide members 19 and 20. An endless conveyor chain 21 is disposed in the space between the channel members 19 and 20 and chain 21 has a series of spacedapart brick-moving lugs 22 secured thereto. The intake or rear end of the chain 21 engages over a rear structure 23 secured to a shaft 24 which is journaled in bearings 25. The bearings 25 are carried by a bracket 26 braced by a bracing bar 27. The opposite end ofthe conveyor chain 21 engages about a driving bracket 28 which is fixed to a shaft 29. Shaft 29 is journaled in bearings 30 ,rice

carried by supporting means 31 extending from the forward legs 12. A relatively large reduction gearing 32 is fixed on shaft 29 and meshes with a smaller driving gear 33 which is fixed on a lower counter-shaft 34. The counter-shaft 34 is journaled in bearings 35 and a relatively large pulley 36 is fixed on shaft 34. A belt 37 engages about pulley 36 and about a driving pulley 38 mounted on a motor shaft 39 which is driven from a motor 40. The motor 40 is supported on a horizontal platform 41 extending between legs 12, 14 and 13. At a point substantially midway of the length of the guide or track 18 there is a tubular boxing 42 which engages about the channel members 18. The boxing 42 has disposed on the outer side thereof a pair of leaf-springs 43 and 44 which project inwardly for yieldable engagement with a brick disposed in confronting position thereto. A chipping wheel 45 is mounted on a shaft 46 jonrnaled in bearings 47. The shaft 46 has a pulley 43 fixed thereon and a belt 49 engages about wheel or pulley 48 and about a driving pulley or wheel 50 mounted on a motor shaft 51. The shaft 5l is rotated from a motor 52 which is fixed on the platform 41. The wheel 45 is an upper chipping wheel and has projecting from the periphery thereof a plurality of brick chipping lugs 53. A second or lower brick chipping wheel 54 is xed on the shaft 55 journaled in bearings 56. A pulley 57 is fixed on shaft 55 and a belt or flexible driving member 53 engages about a pulley or wheel 47 and about a pulley or wheel 59 mounted on a motor shaft 60 driven from a motor 611. Motor 61 is also mounted on platform 41. Wheel 54 has a plurality of brick chipping lugs 62 mounted thereon for engagement with the lower half of the brick face moving through boxing 42. The boxing 42 is formed with an opening 63 through which the lugs 53 are adapted to engage and the boxing 42 is also formed with a second opening 64 through which the lugs 62 are adapted to engage.

In the use and operation of this machine the bricks are fed into the machine from the right end, as viewed in Fig. 1. The brick moving lugs 22 are spaced apart a distance substantially equal to the length of one brick. As each brick enters the boxing 42 the brick will eventually move into a position for contact by the upper wheel lugs 53. These lugs 53 will chip the brick from the outer corner thereof downwardly toward the center of the adjacent face and as the brick moves forwardly an additional distance the lower half of the front face of the brick will come into Contact with the lower brick chipping lugs 62 on wheel 54. The springs 43 and 44 in the boxing 42 Will yieldably hold the bricks against the opposite wall of the boxing so that the brick when being chipped .vill be firmly held in order that the brick will not jump during the chipping operation.

This machine will produce a chipped outer surface on each brick which is known in the trade as rockface, or a chipped surface brick.

What is claimed is:

l. A brick chipping machine comprising a frame, an elongated guide carried by said frame, an endless conveyor movable lengthwise of said guide, a pair of Wheels rotatably carried by said frame in confronting position to one side of said guide, the axis of one wheel being disposed above the axis of the other wheel, a plurality of chipping lugs carried by said wheels, a boxing about said guide confronting said Wheels, said boxing having openings through which said lugs are engageable for contact with an adjacent face of a brick, yieldable means on said boxing confronting said openings for holding the brick against lateral movement during the chipping operation, operating means for said conveyor, and operating means for said wheels.

2. A brick chipping machine comprising a frame, an elongated guide carried by said frame, an endless conveyor movable lengthwise of said guide, a pair of wheels rotatably carried by said frame in confronting position to one side of said guide, means supporting said wheels in vertically spaced relation, a plurality of chippinglugs carried by said wheels, a boxing about said guide confronting said wheels, said boxing having openings through which said lugs are engageable for contact with an adjacent face of a brick, yieldable means in said boxing confronting said openings for holding the bricks against lateral movement during the chipping operation, operating means for said conveyor, and operating means for said wheels.

3. A brick chipping machine comprising a frame, an elongated guide carried by said frame, an endless conveyor movable lengthwise of said guide, a pair of wheels rotatably carried by said frame in confronting position to one side of said guide, a plurality of chipping lugs carried by said wheels, means supporting said wheels in vertically spaced relation whereby the lugs of one wheel will engage the confronting upper corner portion of a brick and the lugs of the other wheel will engage the confronting lower corner portion lof a brick, a boxing about said guide confronting said wheels, said boxing having openings through which said lugs are engageable for contact with an adjacent face of a brick, yieldable means in said boxing confronting said openings for holding the brick against lateral movement during the chipping operation, operating means for said conveyor, and operating means for said wheels.
